03 Springfield built by Joh. Springer, Erbin, Wein built in the mid 50's. Had it re-blued and now the front of the receiver is red, the rear is green and the pistol grip cap is blue and green. Job was done by a local gunsmith in about the mid 1970's. Discussed, I placed it in the safe and haven't looked at in in years. How do get it back to it's original condition?
